EVA M. HOPPE, OF SPARTA, ILLINOIS.

EXTENSION STEP-LADDER.

To all whom it may concern:

Be it known that I, EVA M. HoPPn, a citizen of the United States,residing at Sparta, in the county of Randolph and State of Illinois,have invented a new and useful Extension Step-Ladder, of which thefollowing is a specification.

This invention relates to extension ladders.

The object of the invention is to provide an article of this characterwhich shall be simple of construction, efficient and durable in use, andin which its conversion from a step ladder to an extension ladder mayreadily and easily be effected.

WVith the above and other objects in view, as will appear as the natureof the invention is better understood, the same consists in the novelconstruction and combination of parts of an extension ladder, as will behereinafter fully described and claimed.

In the accompanying drawings forming a part of this specification, andin which like characters of reference indicate corresponding parts :Figure 1 is a view of the device when used as a step ladder. Fig. 2 is asimilar view when used as an extension ladder.

The ladder embodies two ladder sections 1 and 2, the former of which isprovided with a series of flat steps 3 and a plurality of rungs 4, whilethe section 2 is provided only with rungs 5, although if preferred, itmaybe provided with flat steps similar to those shown in section 1.

The two sections carry, as usual, a platform 6, which is connected withthe section 1 by hinges 7 that are secured by screws to the upper endsof the side rails of the section 1 and to the section 2 by clips 8 thatare secured to the under side of the platform and are pivotallyconnected with the upper ends of side rails of the section 2. The latterconnection is secured by slightly reducing the upper ends of the siderail members of the section 2, and securing thereto plates 9 that areorificed, the orifices being designed to register with orifices in theclips 8, and to receive a rod or bar 10, one end of which is providedwith a head 11 and the other end of which is threaded and carriesSpecification of Letters Patent.

a nut (not shown) to hold the rod from accidental disconnection in use.In order to prevent the platform from lifting, should weight be appliednear the outer edge of the platform, hooks 12 are provided that engageeyes 13 on the under side of the platform. To hold the two sections 1and 2 in the desired spaced adjustment, a toothed bar 14 is provided,which is pivotally connected with one of the side rails of the section1, and has its teeth 15 arranged to engage with a pin 16 carried by oneof the side rails of the section 2. Ordinarily, only one of thesetoothed bars will be necessary to hold the two sections at the desiredadjustment, but, as will be evident, two bars may be employed and stillbe within the scope of the invention.

As a means for converting the article from a step ladder to an extensionladder, as shown in Fig. 2, the upper rung 4L supports two hooks 17 thatare designed to be engaged by the lowermost rung 5 of the section 2.l/Vhen the ladder is to be converted into an exten- .sion ladder, therod or bar 10 is removed from engagement with the clips 8, and theplatform 6 is moved at right angles to its normal position, and thesection 2 is inverted to bring its rung 5 into engagement with thesupporting hooks 17. As will be obvious, while this arrangement willsupport the section 2 vertically, yet it would not prevent it frommoving away from the section 2 when placed against awall or the like,and in order to prevent this, four angular arms 18 are provided, thatare rigidly secured to the section 1, and engage with the outer ed es ofthe side rails of the section 2, as clearly shown in Fig. 2.

From the foregoing description it will be seen that although theimprovements herein defined are simple in, character, they will bethoroughly efficient for the purposes designed, and will result in thepresentation of a household article that will meet all the demands of astep ladder and an extension ladder.

I claim An article of the class described comprising two laddersections, a platform hingedly vided on its unoer side With clips beingdein the presence of tWo Witnesses.

signed to be engaged by the upper terminals EVA M HOPPE of the othersection, and a rod engaging the i 5 letter terminals and the clips tohold the two sections assembled.

In testimony that I claim the foregoing as I connected to one of thesections and pro- I my own, I have hereto afiiXed my signature\Vitnesses J. BRANNY, C. A. IVIOLAUGHLIN.
